SouthwestUniversityofScienceandTechnology本科毕业设计（论文）题目：护套成形工艺分析和模具设计学生姓名:王嘉文学生学号:20136062专业:材料成型及控制工程指导教师:金玉萍学院(部):制造科学与工程学院护套成形工艺分析和模具设计摘要模具行业是工业发展中一个不可或缺的部分，而冲压又是模具制造中一种极为重要的方法。利用冲压的方法制造护套制件，会采用到冲压中的落料、拉深、切边以及缩口等一系列工序来共同实现护套的成形过程。为了实现从原材料到护套制件的完整成形过程的还原，以文献研究法为主，利用大学所学习的相关模具制造知识与图书馆翻阅的资料，结合前人的设计经验，对完成制件所需要的工艺方法进行研究分析、研究是否采用复合模提高护套制件成形的生产效率、拉深与缩口时是否一次成形、凸模与凹模的设计是否合理等。经过具体的计算进而比较，从而选择合适的设计过程完成护套制件的制作，最后通过在完成整个设计的过程中了解模具制造的具体过程，积累模具设计的经验。关键词：冲压、落料、拉深、缩口GACKETFORMINGPROCESSANALYSISANDMOLDDESIGNABSTRACTMoldindustryisanindispensablepartofindustrialdevelopment,andstampingisaveryimportantmoldmanufacturingmethod.Theuseofstampingmethodofmanufacturingsheathparts,willbeusedtostampingintheblanking,drawing,trimmingandneckingandaseriesofprocessestoachievethesheathformingprocess.Inordertorealizethereductionofthecompleteformingprocessfromtherawmaterialtothesheathpart,theliteratureresearchmethodismainlyusedtomaketheknowledgeoftherelevantmoldslearnedbytheuniversityandtheinformationofthelibrary,combinedwiththepreviousdesignexperience,Therequiredmethodofresearchandanalysistostudywhethertheuseofcompositemoldtoimprovetheproductionofsheathpartsoftheproductionefficiency,drawingandneckingwhenaforming,punchanddiedesignisreasonableandsoon.Throughthespecificcalculationandthencompare,soastoselecttheappropriatedesignprocesstocompletetheproductionofsheathparts,andfinallythroughthecompletionoftheentiredesignprocesstounderstandthespecificprocessofmoldmanufacturing,molddesignexperience.Keywords:Stamping,blanking,drawing,necking.目录第1章绪论.....................................................................................................................................11.1课题背景............................................................................................................................11.2模具行业的发展现状........................................................................................................11.3冷冲压的现状与发展趋势................................................................................................21.4课题的目的及意义............................................................................................................2第2章护套的成形工艺分析及方案确定.....................................................................................42.1护套及其工艺分析............................................................................................................42.1.1护套二维图及三维图............................................................................................42.1.2护套的工艺分析....................................................................................................42.2工艺方案确定....................................................................................................................5第3章落料拉深模的工艺计算.....................................................................................................63.1拉深前...
